Umbilical Hernia

An umbilical hernia is a bulge at or near the belly button that occurs when tissue, fat or part of the intestine pushes through a weak area in the abdominal wall. It is common in infants and can also affect adults, and treatment depends on age, symptoms, hernia size and the risk of complications.

Overview

An umbilical hernia is a protrusion at the belly button caused by a weakness or small opening in the abdominal wall. Through this opening, abdominal lining, fatty tissue or sometimes part of the intestine can push outward, creating a visible or touchable bulge. The bulge may be soft and may change in size during the day, especially with crying, coughing, lifting, straining or standing.

Umbilical hernias are common in infants because the opening where the umbilical cord passed through the abdominal muscles may not fully close after birth. In many babies, the opening becomes smaller and closes naturally as the child grows. In adults, an umbilical hernia usually develops when pressure inside the abdomen acts on a weakened area around the navel.

Most umbilical hernias are not immediately dangerous, but they should be assessed by a qualified doctor. The main concern is whether tissue becomes trapped in the hernia or its blood supply is affected. A medical evaluation helps determine whether monitoring is appropriate or whether surgical repair is the safer long-term option.

Symptoms

The typical symptom of an umbilical hernia is a swelling or bulge at or close to the belly button. In infants, it may be easiest to see when the baby cries, coughs or strains, and it may become less visible when the baby is relaxed or lying down. In adults, the bulge may be more noticeable when standing, exercising, lifting, coughing or after a large meal.

Some umbilical hernias cause no pain. Others may cause a pulling sensation, pressure, mild discomfort or tenderness around the navel, especially after activity. The skin over the hernia is usually normal, but irritation can occur if clothing rubs on the area or if the hernia is large.

Symptoms that may suggest a complication include increasing pain, swelling that becomes firm, redness or dark discoloration of the skin, nausea, vomiting, abdominal bloating, fever or inability to pass stool or gas. A hernia that was previously soft but can no longer be gently reduced, or pushed back, should be assessed urgently. These signs may indicate incarceration or strangulation, which require prompt medical care.

Causes & Risk Factors

An umbilical hernia develops when a weak area in the abdominal wall allows tissue to protrude. In babies, the cause is usually incomplete closure of the umbilical ring after the umbilical cord falls off. This is not caused by how the cord was cut or cared for, and parents should not feel responsible for the hernia.

In adults, the weakness may be present from childhood or may develop later due to ongoing strain on the abdominal wall. Increased pressure inside the abdomen can gradually widen a small defect, allowing a hernia to appear or enlarge. Some people notice the bulge after weight gain, pregnancy, heavy lifting or a period of severe coughing.

Common risk factors include:

• Pregnancy, especially multiple pregnancies
• Excess body weight or rapid weight changes
• Previous abdominal surgery or scar tissue near the navel
• Chronic cough or long-term straining with constipation
• Heavy lifting or repeated high-pressure abdominal activity
• Fluid buildup in the abdomen from certain medical conditions
• Premature birth or low birth weight in infants

Having a risk factor does not mean a person will definitely develop an umbilical hernia. However, recognizing these factors can help doctors assess the likelihood of progression and plan safe treatment when needed.

Diagnosis

Diagnosis of an umbilical hernia usually begins with a physical examination. The doctor examines the belly button area while the patient is lying down and may also ask the patient to stand, cough or gently strain. This helps show the size of the hernia opening and whether the bulge can be reduced.

The doctor will ask about symptoms such as pain, changes in size, nausea, vomiting, bowel habits, previous surgery, pregnancy, weight changes and work or exercise activities. In children, the doctor may ask whether the bulge changes when the child cries or relaxes, and whether it has grown over time.

Imaging is not always required, but it may be recommended in certain situations. Ultrasound can help confirm the diagnosis and show what tissue is inside the hernia. Computed tomography or other imaging may be used when the hernia is large, recurrent, painful, difficult to examine, associated with previous surgery or when another abdominal condition needs to be considered.

Treatment Options

Treatment for an umbilical hernia depends on the patient’s age, symptoms, hernia size, whether the hernia can be reduced and the person’s overall health. The right approach is decided by a specialist after assessment. A doctor considers both the current symptoms and the future risk of the hernia enlarging or becoming trapped.

In infants and young children, many umbilical hernias are observed because they may close naturally over time. The doctor may recommend regular follow-up to monitor the size and appearance of the hernia. Surgery may be considered if the hernia is very large, painful, causes complications, persists beyond the expected age for closure or has features that make spontaneous closure unlikely.

In adults, umbilical hernias are less likely to close on their own. Observation may be appropriate for some small, symptom-free hernias, but surgical repair is often discussed when the hernia causes discomfort, enlarges, affects daily activity or has a higher risk of complications. Repair aims to close the weakness in the abdominal wall and reduce the chance of recurrence.

Surgical options may include open repair or minimally invasive techniques, depending on the hernia and the patient’s circumstances. Some repairs use sutures alone, while others use a supportive mesh to strengthen the abdominal wall. Decisions about technique, anesthesia, recovery guidance and timing are individualized by the surgical team, particularly for people with obesity, diabetes, smoking history, previous abdominal surgery or other medical conditions.

Living With / Prognosis

Many people live normally with a small umbilical hernia while it is being monitored, but medical follow-up is important. Patients are usually advised to avoid activities that cause pain or marked bulging and to discuss safe levels of exercise, work and lifting with their doctor. Managing constipation, chronic cough and excess abdominal pressure may help reduce discomfort and avoid additional strain.

For adults who need repair, prognosis is generally good when the hernia is treated appropriately and recovery instructions are followed. After surgery, patients may receive guidance about wound care, gradual return to movement, lifting restrictions and when to resume work or sports. Recovery time varies depending on the repair method, hernia size and personal health factors.

Long-term success is supported by healthy lifestyle measures such as maintaining a stable weight, stopping smoking if applicable, treating persistent cough, managing bowel habits and following medical advice for chronic conditions. These steps cannot guarantee that a hernia will not recur, but they may reduce strain on the abdominal wall.

Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat umbilical hernias for international patients, including assessment by general surgery teams when surgical repair is being considered. Care should always be individualized after a clinical evaluation.

When to See a Doctor

A doctor should assess any new bulge around the belly button, even if it is painless. Early evaluation confirms whether the swelling is an umbilical hernia and helps distinguish it from other causes of a navel lump. It also gives patients clear advice about monitoring, activity and treatment options.

Parents should ask a pediatrician to examine a baby or child with a belly button bulge, especially if the hernia seems large, painful, hard, discolored or increasing in size. Adults should seek medical advice if the hernia causes discomfort, interferes with work or exercise, becomes difficult to reduce or changes in appearance.

Urgent medical care is needed if the hernia becomes suddenly painful, firm or tender, if the skin over it turns red, purple or dark, or if the person has vomiting, fever, abdominal swelling, inability to pass stool or gas, or worsening general illness. These symptoms can indicate that tissue is trapped or its blood supply is compromised. Prompt assessment helps prevent serious complications and allows timely treatment.

Frequently asked questions

What is an umbilical hernia?

An umbilical hernia is a bulge at or near the belly button caused by tissue pushing through a weak spot in the abdominal wall. It may contain fat, abdominal lining or part of the intestine. It is common in babies and can also develop in adults.

Can an umbilical hernia heal on its own?

Many umbilical hernias in infants close naturally as the abdominal wall strengthens. In adults, an umbilical hernia usually does not close on its own and may slowly enlarge. A doctor can advise whether observation or repair is appropriate.

Is an umbilical hernia dangerous?

Most umbilical hernias are not immediately dangerous, especially when they are soft, painless and reducible. The main risk is that tissue can become trapped or lose blood supply. Sudden pain, vomiting, skin discoloration or a hernia that cannot be pushed back requires urgent medical attention.

How is an umbilical hernia diagnosed?

Diagnosis is usually made by physical examination of the belly button area. The doctor may check the bulge while the patient is lying down, standing or coughing. Ultrasound or other imaging may be used if the hernia is difficult to assess or if complications are suspected.

What is the treatment for an umbilical hernia?

Treatment may be observation or surgical repair, depending on age, symptoms, size and risk factors. Children are often monitored because many hernias close naturally, while adults more often need discussion with a surgeon. The most suitable option should be decided by a specialist after examination.

Can exercise or lifting make an umbilical hernia worse?

Activities that increase pressure inside the abdomen, such as heavy lifting or intense straining, can make a hernia bulge more or cause discomfort. Patients should avoid movements that trigger pain and ask their doctor about safe activity levels. After surgery, return to exercise should follow the surgeon’s recovery plan.

When should someone seek urgent care for an umbilical hernia?

Urgent care is needed if the hernia becomes severely painful, hard, red, purple or dark, or if it cannot be gently pushed back. Vomiting, fever, abdominal swelling or inability to pass stool or gas are also warning signs. These symptoms may indicate incarceration or strangulation and should not be ignored.
